Expand description

Deserialize a Vec<T> field, treating an explicit JSON null the same as an empty array. Required because the ClickHouse Cloud API emits null for some array-valued fields that its OpenAPI spec declares as non-nullable arrays (e.g. reversePrivateEndpointIds on Kafka sources). With plain #[serde(default)], a missing field works but an explicit null fails with “invalid type: null, expected a sequence”.
